  • the noninflatable chamber has a spatial orientation which is different from the spatial orientation of the inflatable chamber when inflated.
  • the figure assumes the shape of the noninflatable chamber, when the inflatable chamber is inflated, however, the inflation of the chamber causes all or a part of the figure to assume a different position, dependent upon the level of inflation of that chamber.
  • the exterior chamber will be the noninflatable chamber and the interior chamber will be the inflatable chamber, although the reverse configuration could be employed, although with more difficulty.
  • a single, inflatable chamber is employed, said chamber having section of one wall which is less elastic than the remainin portion of the wall. Due to the differential in elasticity upon inflation the chamber assumes a shape or configuration which is different from the noninflated chamber.
  • two collapsible, fluid chambers and associated means for controlling the fluid pressure in each of said chambers are provided.
  • the chambers are each helically wound in opposite directions and placed substantially parallel to one another.
  • one end of each chamber is rigidly mounted so that rotation each respective chamber at that point is not possible.

  • the compositi of the chamber is not critical as long as it is flexible a collapsible over repeated cycles of inflation and deflatio
  • the collapsible chambers should be as fluid-tight as possible, to minimize the energy necessary to change and maintain the chambers in a state of inflation or deflation
  • the fluid necessary to cause the inflation or_deflation of chambers likewise is not critical, although for ease and simplicity of design, fabrication, and operation, it is preferred to use air to inflate the chambers.
  • the pressur maintained in the chambers when inflated likewise is not critical and any pressure over atmospheric is desirable, s as from about 2 to about 200 psi. Essentially, there is n limitation upon the amount of pressure which may be employ as the components of the system may be varied in design to accommodate the desired pressure.
  • the amount of pressure employed to inflate a chamber is directly translatable int the amount of strength which may be exhibited by the anima character. Further, the pressure differential maintained between inflated chambers and deflated chambers is directl translatable into speed. The greater the differential, th more quickly that a given chamber can inflate and a second chamber, if present, deflate, allowing the figure to rapid change in outward appearance.

  • the valves are of the type which are either fully open or fully closed, although in some applications valves capable of being placed in partially open positions may be employed. In typical operation, when the valve to one of the collapsible chambers is placed in a close position, the valve associated with the opposing chamber is placed in an open position.
  • both inflatable chambers may be locate within a third, encasing chamber which itself is not directly inflated.
  • both of the chambers are maintained in close physical proximity along their length and thus each chamber, upon inflation, may exert an immediate opposing force upon the other chamber along the entire length of the respective chambers.
  • the outside spatial configuratio assumed by the third chamber which houses the two inflatable chambers is determined by the degree of inflation of each of the internal, inflatable chambers.
  • more than two inflatable chambers may be employed within the exterior, encasing chamber.
  • a single, inflatable chamber is employed, said chamber having a section of one wall which is less elastic than the remaining portion of the wall. Due to. the differential in elasticity, upon inflation the chamber assumes a shape or configuration which is different from the chamber when noninflated.
  • the chamber may be constructed and employ in the same fashion as the inflatable chambers used in accordance with the first aspect of the present invention, except that the chamber has one or more wall regions which a less elastic than the remaining wall area.
  • the wall regions of less elasticity may be achieved by any number of methodologies.
  • a section of the wall of the chamber has a thickened region wherein the wall thickness is greater than that of the remaining wall.

  • the thickening is from about 1 to about 10 orders of magnitude, comparison to the thickness of the chamber-s remaining wall regions.
  • the particular wall section of lowered elasticity may be comprised of a material which is simply less elastic than that of the remaining wall regions. Modification of the surface properties of the wall may also employed, as by application of inelastic coating composition or the like, in order to achieve the desired lowered elasticity of a portion of the wall.

Abstract

Dans un mode de réalisation du procédé et de l'appareil, on utilise une pluralité de chambres gonflables de fluide (120, 130) et des moyens associés (140, 150) pour régler la pression de fluide dans chaque chambre (120, 180). Au moins deux de ces chambres sont physiquement agencées de sorte que le gonflement d'une des chambres et le dégonflement de l'autre chambre complémentaire amènent un personnage (110) ou une partie d'un personnage à prendre une position spatiale différente qui dépend du niveau de gonflement de chaque chambre. Dans un autre mode de réalisation, on utilise une seule chambre gonflable dont une paroi a une section moins élastique que la partie restante de la paroi. Compte-tenu de la différence d'élasticité, lorsque la chambre est gonflée elle prend une forme ou un agencement différent de celui de la chambre non gonflée. Dans un troisième mode de réalisation, deux chambres (540, 550) gonflables de fluide sont enroulées en spirale dans des directions opposées, sensiblement parallèles. Lorsqu'une pression de fluide est appliquée à l'une ou à l'autre chambre (540, 550), ladite chambre se met en rotation, déroulant des spires hélicoïdales tout en serrant dans une même mesure les spires de l'autre chambre.
